(and verifiable) data fitting methods, such as those proposed by Graham et al [Scibetta (2004), Graham (2011)]. Similarly there remains an onus on data analysis to seek the best part of the data; equally on equipment manufacturers and test technicians alike, to ensure good design and set up of equipment.
